Question
A concerned group of citizens wanted to know if the proportion of armed robberies in Texas was different
in 2011 than in 2010. Their research showed that of the 113,231 violent crimes in Texas in 2010, 7,622 of
them were armed robberies. In 2011, 7,439 of the 104,873 violent crimes were in the armed robbery
category. Test at a 5% significance level.
a) The null and alternative hypothesis would be:
O Ho: #2010
H1: H2010 > H2011
H2011
O Ho: P2010
H1: P2010 < P2011
P2011
O Ho: 42010
H1: 42010 < u2011
l2011
O Ho:P2010 = P2011
H1: P2010 + P2011
O Ho: H2010 = H2011
H1: 42010 + 42011
O Ho:P2010 = P2011
H1: P2010 > P2011
b) Determine the test statistic. Round to two decimals.
c) Find the p-value and round to 4 decimals.
d) Make a decision.
O Reject the null hypothesis
O Fail to reject the null hypothesis
